Answer:
x = 2.5.
y = 5.
Step-by-step explanation:
As they are image and pre-image of a dilation they are similar triangles, so the corresponding sides are in the same ratio.
4/2 = 5/x
2 = 5/x
2x = 5
x = 2.5.
Also:
4/2 = (y + 1)/ 3
2 = (y + 1) / 3
y + 1 = 6
y = 5.

Pythagoras theorem I guess
There is 20% decrease in the number of members.
Step-by-step explanation:
Given,
Members last year = Old value = 30
Members this year = New year = 24
Change = New value - Old value
Change = 24 - 30
Change = -6
The negative sign indicates the decrease.
Decrease percent = 
Decrease percent = 
Decrease percent = 
Decrease percent = 20%
There is 20% decrease in the number of members.
